In the top of described some truss 7, described some truss 7 spaced sets contact on longeron 6 in described some truss, described purlin
It is perpendicular that frame 7 and described truss contact longeron 6.Described truss 7, truss contact longeron 6, bed die connect channel-section steel 8 and sidepiece bottom
Mould 9 is overall can be prefabricated in advance together in factory.For the ease of transport it is also possible to first by truss 7, bed die connect channel-section steel 8 with
And sidepiece bed die 9 is prefabricated in the factory together, to after building site in the lower section that truss contact longeron 6 is assembled into described truss 7, with
Convenient transport.
Preferably, in above-mentioned overpass bent cap sizing bed die support, if described truss contact longeron 6 be arranged at described
On dry root post top contact crossbeam 5, and to contact crossbeam 5 perpendicular described truss contact longeron 6 and described some root post tops.
So that described column top contact longeron 4 contacts crossbeam 5 and the more firm support institute of column 2 with described column top
State sizing bed die bracing frame, described column top contact longeron 4 is preferably Two bors d's oeuveres 36a I-steel, and cross section parameter is h=360mm t
=15.8mm b=136mm, d=10mm, per pass column top contacts a length of 3m of longeron 4；Described column top contact crossbeam 5 adopts
36a I-steel, cross section parameter is h=360mm t=15.8mm b=136mm, d=10mm, lays spacing 600mm；Described vertical
Post 2 is the steel pipe of φ 609mm × 16mm, and spacing is 2m.
Preferably, in above-mentioned overpass bent cap sizing bed die support, the lower section of described column 2 is provided with strip footing 1.
So that described strip footing 1 preferably supports described column 2 and all parts thereon, in the present embodiment, described bar shaped
The section on basis 1 is preferably dimensioned to be 3000*600*500, and the dimensional units in section are mm.
Please continue to refer to Fig. 1 to Fig. 2, the present embodiment also discloses a kind of overpass bent cap sizing bed die as above and props up
The using method of frame, is set for supporting the midfoot support frame of middle part bed die 10 (not scheme using existing conventional method in advance
Show), the using method of described overpass bent cap sizing bed die support, comprise the steps,
The first step, installs column 2 in the strip footing 1 planning to build overpass bent cap both sides；
Second step, is respectively mounted jack 3 on each column 2；
3rd step, is respectively provided with described column top contact beam assembly on the jack 3 planning to build overpass bent cap 11 both sides；
4th step, the left and right sides sizing bed die bracing frame of the sidepiece bed die 9 with bent cap is respectively arranged in corresponding standing
On capital contact beam assembly.Thus the erection work of all bed dies of bent cap 11, then the side form (not shown) of bent cap 11 is set, with
Realize the casting craft of bent cap.The both sides bed die of middle bent cap is by way of bent-frame bracing compared to existing technology, lid of the present invention
The both sides bed die 9 of beam 11 is supported by overpass bent cap sizing bed die support, and both sides bed die 9 is formed on described sizing bottom in advance
On mould bracing frame, thus scene eliminates a large amount of aloft work amounts adjusting framed bent absolute altitude, effectively increases the construction effect of bent cap
Rate, and improve the safety of Coping Construction.
In sum, the present embodiment has the advantages that
1) progress monitoring aspect: in overpass Coping Construction, safe construction is extremely important.Originally using setting up a Pin bent cap
Template framed bent need 8 days construction periods, also want the absolute altitude of constantly regulate steel pipe framed bent during setting up, the present invention uses bed die instead calmly
After type bed die bracing frame, the template system of a Pin bent cap 3 days just can installation.Sizing bed die bracing frame is in advance according to bent cap bottom
Absolute altitude setting processing, therefore need not carry out the regulation of absolute altitude in construction, after steel pipe post installation, settling at one go will be fixed
Type bed die bracing frame installation.
2) cost control aspect: after present invention setting sizing bed die bracing frame, make sidepiece bed die in factory's preprocessing
It is welded on sizing bed die bracing frame, on-site hoisting is located in ф 609 steel pipe post system.Whole engineering has 53 Pin bent caps,
Constructed using 3 sets of bed dies sizing bed die bracing frame turnovers.Average often set bed die sizing bed die bracing frame can have enough to meet the need and turn over use
17 times.Set up 10 scaffolders of needs according to conventional framed bent system one Pin bent cap bed die to set up, using sizing bed die bracing frame only
2 scaffolder cooperation electric welders are needed to install.The existing market quantity of labour force is in short supply, and labour cost unit price is high.Sizing bed die bracing frame
Labour force can be reduced and save cost of labor.
3) security control aspect: existing conventional scaffolding steel pipe framed bent sizing bed die bracing frame system is set up process and belonged to
Work high above the ground, is major hazard source, and steel pipe framed bent accident rate is higher.And after the present invention is using sizing bed die bracing frame, can evade
The globality of this kind of dangerous matter sources and bed die bracing frame of shaping is more preferable.
Foregoing description is only the description to present pre-ferred embodiments, not any restriction to the scope of the invention, this
Any change that the those of ordinary skill in bright field does according to the disclosure above content, modification, belong to the protection of claims
Scope.
